  author={Osamu Kameyama and K Shibano and Hiroaki Kawakita and Ryokei Ogawa},
Study Design. This study investigated the clinical usefulness of motor evoked potentials and a silent period after motor evoked potentials produced by transcranial magnetic stimulation of the brain. Objective. The results were correlated with the clinical state of the patients with myelopathy, whereas no abnormality of the conduction time was observed in the patients with spinal canal stenosis. Summary of Background Data. Magnetic stimulation has been widely used for examination of the… 
Coexisting Peripheral Nerve and Cervical Cord Compression
Measurement of the central motor conduction time using motor evoked potentials is an ideal diagnostic approach for patients with coexisting entrapment neuropathy and cervical cord compression.
Superior sensitivity of motor over somatosensory evoked potentials in the diagnosis of cervical spondylotic myelopathy
The value of functional assessment of the spinal cord by motor and sensory evoked potentials (MEP and SEP) in the detection of myelopathy, with special emphasis on the correlation of clinical and electrophysiological findings, is analyzed to help clinicians in interpreting MRI signs of cervical spinal cord compression.
The value of somatosensory and motor evoked potentials in pre-clinical spondylotic cervical cord compression
Combined SEPs and MEPs proved to be a valuable tool in the assessment of the functional relevance of subclinical spondylotic cervical cord compression.
Quantitative assessment of myelopathy patients using motor evoked potentials produced by transcranial magnetic stimulation
MEP abnormalities are useful for an electrophysiological evaluation of myelopathy patients and may be effective parameters in spinal pathology for deciding the operative treatment.
Assessment of Cervical Myelopathy Using Transcranial Magnetic Stimulation and Prediction of Prognosis After Laminoplasty
In patients with cervical myelopathy, the CMCT significantly correlated with the results of clinical assessment, and may be useful parameters in spinal pathology for prediction of the outcome of surgical treatment.
Transcranial Magnetic Stimulation of the Motor Cortex Correlates With Objective Clinical Measures in Patients With Cervical Spondylotic Myelopathy
CMCT as measured by transcranial magnetic stimulation is a responsive objective assessment of CSM and can be used to monitor disease severity and neurological function before and after surgical intervention.
Motor and somatosensory evoked potentials in asymptomatic spondylotic cord compression
MEPs and SEPs are normal in most cases of asymptomatic cervical stenosis, and data indicate that MEP and SEP may be clinically useful for differentiating patients with cervical stenotic who have myelopathy from those who have not.
Motor conduction alterations in patients with lumbar spinal stenosis following the onset of neurogenic claudication
Exercise increases the sensitivity of MEPs in detecting the roots under functional compression in LSS, and there was a significant difference between the MEPLT and the PMCT values measured before and after exercise in patients with signs of neurological deficit.
Systematic Correlation of Transcranial Magnetic Stimulation and Magnetic Resonance Imaging in Cervical Spondylotic Myelopathy
Transcranial magnetic stimulation showed excellent correlation with magnetic resonance Imaging findings and can be considered as an effective technique for screening patients for cervical cord abnormalities before magnetic resonance imaging in the clinical setting.
